What is WiFi security?

WiFi security is the protection of wireless networks from unauthorized access and cyber threats. It involves encryption, authentication, and other measures to ensure that data transmitted over WiFi remains private and secure.

Which of the following best describes what WiFi security is?

WiFi security is designed to stop unauthorized access and protect data transmitted over wireless networks from eavesdropping and cyber threats.

Why is WiFi Security so important?

Ignoring WiFi security can open the door to serious risks. Public and fake networks can be traps, and weak router passwords or outdated settings leave you exposed. To stay safe, secure your router, use strong WiFi passwords, and keep router firmware up to date.

Public WiFi Networks

Public WiFi, such as those found in cafes, airports, or hotels, is often easy to access but not always safe. Cybercriminals can intercept data on unsecured networks, exposing your passwords, emails, and personal information. Easy access does not always mean secure access.

You're connected to public WiFi in a cafe. Which activity poses the GREATEST risk on this network?

Accessing your online banking account is one of the highest-risk operations you can do on the internet. On public WiFi, cybercriminals may attempt to insert themselves in the login process to steal your credentials. Only ever access online banking accounts from networks you know and trust.

Strong Router Passwords

Routers often use weak default passwords that attackers can easily guess. Sometimes they are printed right on the box. Changing it to something long, unique and hard to guess helps keep your network secure.

Configure Router’s Settings Correctly

Your router manages your WiFi network and plays a big role in its security. To stay protected, use strong encryption like WPA3 and disable features you do not need, such as WPS or remote access.

Keep Your Router Firmware Updated

Like your phone or computer, your router needs regular updates. Firmware patches fix security flaws that attackers can exploit. Ignoring updates could make your network vulnerable.

Which of the following best improves your router’s overall security?

Enabling WPA3 encryption and regularly updating firmware is the correct option. WPA3 provides strong encryption to protect your data, and firmware updates patch security flaws that attackers could exploit. These steps directly improve your router’s security, unlike the other options, which don’t address real threats.

Watch Out For Fake WiFi Networks

Attackers can set up rogue WiFi hotspots that look like legitimate networks. These “evil twin” networks trick users into connecting and steal their data. Always double-check the network name and never reconnect blindly.

Is the following statement True or False:
If a WiFi network you’ve already connected to suddenly asks you to log in again, it could be a fake.

A sudden re-authentication request can be a sign that a malicious clone network is in play.

Is the following statement True or False:
Public WiFi is safe to use as long as it has a password.

A password alone does not make a network safe. Always make sure the network you connect to is trusted. Avoid joining random or unfamiliar networks, even if they are password protected.

Which of the following is the most accurate reason why public WiFi can be dangerous?

Attackers may attempt to intercept and sniff unencrypted internet traffic. In extreme cases, attackers will even break encryption on your internet traffic to insert themselves in the middle and present you with fake websites. A common sign of this is your browser suddenly displaying a broken HTTPS connection.
